Barrier Film

Shelf life and the protection of sensitive packed goods are increasingly important in modern packaging applications. High diffusion barrier to protect the packed goods from various external influences, especially oxygen and water vapour barrier, is a crucial topic in food packaging and other industries.

We offer a variety of polyester barrier film types with excellent gas barrier properties under the HOSTAPHAN® brand. The oxygen barrier of transparent polyester barrier film is by far better than competitive film materials like oriented polypropylene or polyethylene. This, together with its superior surface and mechanical properties, is why polyester film is a basic part of Duplex and Triplex barrier film laminates (e.g. PE/PET or PE/PET/ALU). Such laminates are used for example in coffee, soup or dressing packaging or pet food pouches. Even retorting is possible without loosing the excellent barrier properties.
